Listen to the episodeAbout Primer
Primer is a London-based fintech startup building a unified layer across the global payments ecosystem. Its platform allows merchants to connect processors, acquirers, fraud tools, checkout, reconciliation and finance workflows into a single infrastructure. The $100M Series C reinforces the company's core thesis: AI in payments only works when it operates on complete, contextual and non-fragmented data. For Scalable, Primer matters because it shows how fintech infrastructure is becoming AI infrastructure for operational decisions across conversion, fees, fraud, reconciliation and treasury.
The Story
Primer was founded in 2020 by Gabriel Le Roux and Paul Anthony, former Braintree and PayPal executives, to solve the fragmentation of payment systems used by global merchants.
How Primer works

Moat (Defensibility)

Key Risks

- Risk of overstating AI agent autonomy in critical financial workflows

Lessons from Primer
